Fixing I2C problems in framework-arduinoespressif32

Hi!
It seems that official ESP32 Arduino framework consists of broken I2C support. AFAIK GitHub - stickbreaker/arduino-esp32: Arduino core for the ESP32 fork has updated files for fixing ESP32 arduino I2C problems.

Sorry for repeating my question from the previous topic: Is it somehow possible to manually clone/update GitHub - stickbreaker/arduino-esp32: Arduino core for the ESP32 to C:.….platformio\packages\framework-arduinoespressif32? Unfortunately Github Desktop doesn’t allow to use that path (giving error that this path already exists)?

http://docs.platformio.org/en/latest/platforms/espressif32.html#using-arduino-framework-with-staging-version

@ivankravets sorry but that still doesn’t fix it for me.
https://github.com/espressif/arduino-esp32/tree/stickbreaker-i2c version has the fix…
